This application claims the benefit of U.S. Provisional Patent Application Ser. No. 62/830,937, filed Apr. 8, 2019, which is hereby incorporated by reference in its entirety.

BACKGROUND 1. Field of the Disclosure

This technology generally relates to methods and systems for processing time series data signals, and more particularly, to methods and systems for identifying signals or patterns in time series data by treating the series as an image.

2. Background Information

Traders execute buy and sell orders of securities while observing charts of time-series data, such as data that indicates a history of a price of a particular stock. Various algorithms have been developed for the purpose of analyzing such time-series data in order to improve a trader's ability to make a determination as to whether to buy or not buy a particular stock. Conventional algorithms process the time-series data as a list of numerical data.

When a human trader views the time-series data, it is generally displayed in graphical form, and may appear as a jagged line that has an overall trend in an upward or downward direction, similar to a noisy signal. In this aspect, when the human trader uses such a display to determine whether or not to buy a stock, the data may be processed as an image, instead of as a series of numbers.

Accordingly, there is a need for a method for automatically processing time-series data as an image, in order to accurately and efficiently capture the decisions that would likely be made by a human trader when viewing such data.

For example, the computer device 120 may be the same or similar to the computer system 102. Furthermore, those skilled in the art similarly understand that the device may be any combination of devices and apparatuses.

Of course, those skilled in the art appreciate that the above-listed components of the computer system 102 are merely meant to be exemplary and are not intended to be exhaustive and/or inclusive. Furthermore, the examples of the components listed above are also meant to be exemplary and similarly are not meant to be exhaustive and/or inclusive.

In accordance with various embodiments of the present disclosure, the methods described herein may be implemented using a hardware computer system that executes software programs. Further, in an exemplary, non-limited embodiment, implementations can include distributed processing, component/object distributed processing, and parallel processing. Virtual computer system processing can be constructed to implement one or more of the methods or functionality as described herein, and a processor described herein may be used to support a virtual processing environment.

As described herein, various embodiments provide optimized methods and systems for identifying signals or patterns in time series data by treating the series as an image.

Referring to FIG. 2, a schematic of an exemplary network environment 200 for implementing a method for identifying signals or patterns in time series data by treating the series as an image is illustrated. In an exemplary embodiment, the method is executable on any networked computer platform, such as, for example, a personal computer (PC).

The method for identifying signals or patterns in time series data by treating the series as an image may be implemented by a Time-Series Data Image Processing (TSDIP) device 202. The TSDIP device 202 may be the same or similar to the computer system 102 as described with respect to FIG. 1. The TSDIP device 202 may store one or more applications that can include executable instructions that, when executed by the TSDIP device 202, cause the TSDIP device 202 to perform actions, such as to transmit, receive, or otherwise process network messages, for example, and to perform other actions described and illustrated below with reference to the figures. The application(s) may be implemented as modules or components of other applications. Further, the application(s) can be implemented as operating system extensions, modules, plugins, or the like.

Even further, the application(s) may be operative in a cloud-based computing environment. The application(s) may be executed within or as virtual machine(s) or virtual server(s) that may be managed in a cloud-based computing environment. Also, the application(s), and even the TSDIP device 202 itself, may be located in virtual server(s) running in a cloud-based computing environment rather than being tied to one or more specific physical network computing devices. Also, the application(s) may be running in one or more virtual machines (VMs) executing on the TSDIP device 202. Additionally, in one or more embodiments of this technology, virtual machine(s) running on the TSDIP device 202 may be managed or supervised by a hypervisor.

In the network environment 200 of FIG. 2, the TSDIP device 202 is coupled to a plurality of server devices 204(1)-204(n) that hosts a plurality of databases 206(1)-206(n), and also to a plurality of client devices 208(1)-208(n) via communication network(s) 210. A communication interface of the TSDIP device 202, such as the network interface 114 of the computer system 102 of FIG. 1, operatively couples and communicates between the TSDIP device 202, the server devices 204(1)-204(n), and/or the client devices 208(1)-208(n), which are all coupled together by the communication network(s) 210, although other types and/or numbers of communication networks or systems with other types and/or numbers of connections and/or configurations to other devices and/or elements may also be used.

The communication network(s) 210 may be the same or similar to the network 122 as described with respect to FIG. 1, although the TSDIP device 202, the server devices 204(1)-204(n), and/or the client devices 208(1)-208(n) may be coupled together via other topologies. Additionally, the network environment 200 may include other network devices such as one or more routers and/or switches, for example, which are well known in the art and thus will not be described herein. This technology provides a number of advantages including methods, non-transitory computer readable media, and TSDIP devices that efficiently implement a method for identifying signals or patterns in time series data by treating the series as an image.

By way of example only, the communication network(s) 210 may include local area network(s) (LAN(s)) or wide area network(s) (WAN(s)), and can use TCP/IP over Ethernet and industry-standard protocols, although other types and/or numbers of protocols and/or communication networks may be used. The communication network(s) 210 in this example may employ any suitable interface mechanisms and network communication technologies including, for example, teletraffic in any suitable form (e.g., voice, modem, and the like), Public Switched Telephone Network (PSTNs), Ethernet-based Packet Data Networks (PDNs), combinations thereof, and the like.

The TSDIP device 202 may be a standalone device or integrated with one or more other devices or apparatuses, such as one or more of the server devices 204(1)-204(n), for example. In one particular example, the TSDIP device 202 may include or be hosted by one of the server devices 204(1)-204(n), and other arrangements are also possible. Moreover, one or more of the devices of the TSDIP device 202 may be in a same or a different communication network including one or more public, private, or cloud networks, for example.

The plurality of server devices 204(1)-204(n) may be the same or similar to the computer system 102 or the computer device 120 as described with respect to FIG. 1, including any features or combination of features described with respect thereto. For example, any of the server devices 204(1)-204(n) may include, among other features, one or more processors, a memory, and a communication interface, which are coupled together by a bus or other communication link, although other numbers and/or types of network devices may be used. The server devices 204(1)-204(n) in this example may process requests received from the TSDIP device 202 via the communication network(s) 210 according to the HTTP-based and/or JavaScript Object Notation (JSON) protocol, for example, although other protocols may also be used.

The server devices 204(1)-204(n) may be hardware or software or may represent a system with multiple servers in a pool, which may include internal or external networks. The server devices 204(1)-204(n) hosts the databases 206(1)-206(n) that are configured to store historical market data, such as price data for individual securities and/or market indexes, and pattern matching data, which includes data that relates to images of time-series data that is usable for performing pattern matching with market data in order to facilitate decisions regarding whether to buy a security.

Although the server devices 204(1)-204(n) are illustrated as single devices, one or more actions of each of the server devices 204(1)-204(n) may be distributed across one or more distinct network computing devices that together comprise one or more of the server devices 204(1)-204(n). Moreover, the server devices 204(1)-204(n) are not limited to a particular configuration. Thus, the server devices 204(1)-204(n) may contain a plurality of network computing devices that operate using a master/slave approach, whereby one of the network computing devices of the server devices 204(1)-204(n) operates to manage and/or otherwise coordinate operations of the other network computing devices.

The server devices 204(1)-204(n) may operate as a plurality of network computing devices within a cluster architecture, a peer-to peer architecture, virtual machines, or within a cloud architecture, for example. Thus, the technology disclosed herein is not to be construed as being limited to a single environment and other configurations and architectures are also envisaged.

The plurality of client devices 208(1)-208(n) may also be the same or similar to the computer system 102 or the computer device 120 as described with respect to FIG. 1, including any features or combination of features described with respect thereto. For example, the client devices 208(1)-208(n) in this example may include any type of computing device that can interact with the TSDIP device 202 via communication network(s) 210. Accordingly, the client devices 208(1)-208(n) may be mobile computing devices, desktop computing devices, laptop computing devices, tablet computing devices, virtual machines (including cloud-based computers), or the like, that host chat, e-mail, or voice-to-text applications, for example. In an exemplary embodiment, at least one client device 208 is a wireless mobile communication device, i.e., a smart phone.

The client devices 208(1)-208(n) may run interface applications, such as standard web browsers or standalone client applications, which may provide an interface to communicate with the TSDIP device 202 via the communication network(s) 210 in order to communicate user requests and information. The client devices 208(1)-208(n) may further include, among other features, a display device, such as a display screen or touchscreen, and/or an input device, such as a keyboard, for example.

Although the exemplary network environment 200 with the TSDIP device 202, the server devices 204(1)-204(n), the client devices 208(1)-208(n), and the communication network(s) 210 are described and illustrated herein, other types and/or numbers of systems, devices, components, and/or elements in other topologies may be used. It is to be understood that the systems of the examples described herein are for exemplary purposes, as many variations of the specific hardware and software used to implement the examples are possible, as will be appreciated by those skilled in the relevant art(s).

One or more of the devices depicted in the network environment 200, such as the TSDIP device 202, the server devices 204(1)-204(n), or the client devices 208(1)-208(n), for example, may be configured to operate as virtual instances on the same physical machine. In other words, one or more of the TSDIP device 202, the server devices 204(1)-204(n), or the client devices 208(1)-208(n) may operate on the same physical device rather than as separate devices communicating through communication network(s) 210. Additionally, there may be more or fewer TSDIP devices 202, server devices 204(1)-204(n), or client devices 208(1)-208(n) than illustrated in FIG. 2.

In addition, two or more computing systems or devices may be substituted for any one of the systems or devices in any example. Accordingly, principles and advantages of distributed processing, such as redundancy and replication also may be implemented, as desired, to increase the robustness and performance of the devices and systems of the examples. The examples may also be implemented on computer system(s) that extend across any suitable network using any suitable interface mechanisms and traffic technologies, including by way of example only teletraffic in any suitable form (e.g., voice and modem), wireless traffic networks, cellular traffic networks, Packet Data Networks (PDNs), the Internet, intranets, and combinations thereof.

The TSDIP device 202 is described and shown in FIG. 3 as including a time-series data image processing module 302, although it may include other rules, policies, modules, databases, or applications, for example. As will be described below, the time-series data image processing module 302 is configured to implement a method for identifying signals or patterns in time series data by treating the series as an image in an automated, efficient, scalable, and reliable manner.

An exemplary process 300 for implementing a provision of an instrument that facilitates transactions based on a user's intent with respect to a proposed event or experience by utilizing the network environment of FIG. 2 is shown as being executed in FIG. 3. Specifically, a first client device 208(1) and a second client device 208(2) are illustrated as being in communication with TSDIP device 202. In this regard, the first client device 208(1) and the second client device 208(2) may be “clients” of the TSDIP device 202 and are described herein as such. Nevertheless, it is to be known and understood that the first client device 208(1) and/or the second client device 208(2) need not necessarily be “clients” of the TSDIP device 202, or any entity described in association therewith herein. Any additional or alternative relationship may exist between either or both of the first client device 208(1) and the second client device 208(2) and the TSDIP device 202, or no relationship may exist.

Further, TSDIP device 202 is illustrated as being able to access a historical market data repository 206(1) and a pattern matching database 206(2). The time-series data image processing module 302 may be configured to access these databases for implementing a method for identifying signals or patterns in time series data by treating the series as an image.

The first client device 208(1) may be, for example, a smart phone. Of course, the first client device 208(1) may be any additional device described herein. The second client device 208(2) may be, for example, a personal computer (PC). Of course, the second client device 208(2) may also be any additional device described herein.

The process may be executed via the communication network(s) 210, which may comprise plural networks as described above. For example, in an exemplary embodiment, either or both of the first client device 208(1) and the second client device 208(2) may communicate with the TSDIP device 202 via broadband or cellular communication. Of course, these embodiments are merely exemplary and are not limiting or exhaustive.

Upon being started, the time-series data image processing module 302 executes a process for identifying signals or patterns in time series data by treating the series as an image. An exemplary process for identifying signals or patterns in time series data by treating the series as an image is generally indicated at flowchart 400 in FIG. 4.

In the process 400 of FIG. 4, at step S402, the time-series data image processing module 302 identifies patterns of interest that are included in historical market data. For example, referring to FIG. 5, historical market data is illustrated, and three inset boxes are marked for portions of the historical market data in which a pattern of interest has been identified. In an exemplary embodiment, a respective label is attached to each of the identified patterns.

At step S404, the identified patterns are converted into images. In particular, although the historical market data may be originally provided as numerical data or digital data, each subset of data may be converted into an image that resembles a jagged curved line, i.e., a graphical curve that appears to rise and fall as a function of time, and that may resemble a graphical depiction that would typically be viewed by a human analyst. In an exemplary embodiment, each image that corresponds to a pattern is also provided with a respective label.

At step S406, the time-series data image processing module 302 receives new time-series data. Then, at step S408, the newly received data is converted into an image. For example, if a user is interested in analyzing a particular market security for a purpose of determining whether or not to buy the security, a set of recent price data for the security may be received and converted into an image.

At step S410, the pattern images (i.e., the results of step S404) are compared with a section of the newly generated image (i.e., the result of step S408) that corresponds to the most recent time interval. Then, at step S412, the time-series data image processing module 302 determines whether a buying opportunity and/or a selling opportunity is available based on whether there is a match between the image that corresponds to the newly received data and any of the pattern images. For example, if a first pattern image corresponds to a situation that indicates a buying opportunity, and the image that corresponds to the newly received data sufficiently matches the first pattern image, then the time-series data image processing module 302 may determine that a buy recommendation for the market security is indicated. As another example, if a second pattern image corresponds to a situation that indicates a selling opportunity, and the image that corresponds to the newly received data sufficiently matches the second pattern image, then the time-series data image processing module 302 may determine that a sell recommendation for the market security is indicated.

Alternatively, the pattern matching may be performed with respect to other types of market conditions, such as market volatility, market calmness, economic growth, recession, and/or any other suitable types of market conditions. For example, in an alternative exemplary embodiment, at step S412, the time-series data image processing module 302 may determine whether market volatility and/or market calmness is indicated based on whether there is a match between the image that corresponds to the newly received data and any of the pattern images. In this aspect, if a first pattern image corresponds to a situation that indicates market volatility, and the image that corresponds to the newly received data sufficiently matches the first pattern image, then the time-series data image processing module 302 may determine that market volatility is indicated. As another example, if a second pattern image corresponds to a situation that indicates market calmness, and the image that corresponds to the newly received data sufficiently matches the second pattern image, then the time-series data image processing module 302 may determine that market calmness is indicated.

As another example, in another alternative exemplary embodiment, at step S412, the time-series data image processing module 302 may determine whether economic growth and/or a recession is indicated based on whether there is a match between the image that corresponds to the newly received data and any of the pattern images. In this aspect, if a first pattern image corresponds to a situation that indicates economic growth, and the image that corresponds to the newly received data sufficiently matches the first pattern image, then the time-series data image processing module 302 may determine that economic growth is indicated. As another example, if a second pattern image corresponds to a situation that indicates a recession, and the image that corresponds to the newly received data sufficiently matches the second pattern image, then the time-series data image processing module 302 may determine that a recession is indicated.

In an exemplary embodiment, the historical market data may include pricing data for the list of S&P 500 companies. The list of S&P 500 companies includes common stocks that are issued by large-capitalization companies and are actively traded on American stock exchanges. The capitalization of these companies covers approximately 80% of the overall American equity market.

The historical market data may be obtained by querying the High, Low, Open, and Close (hereinafter “HLOC”) dollar values for each of the S&P 500 companies for a particular time frame, such as, for example, Jan. 1, 2010 to Dec. 31, 2018. The obtained time-series data may be discretized to the daily HLOC values, and may be depicted by using a box-and-whisker diagram (also referred to herein as a candlestick diagram), in which box edges mark the Open and Close prices and the whiskers mark the Low and High daily values. In an exemplary embodiment, when the box is filled in with a gray color, the daily Open price was higher than the Close price for that day, and when the box is filled in with a white color, the daily Open price was lower than the Close price for that day.

In an exemplary embodiment, three “buy” indicators and three “sell” indicators may be determined based on an algorithm that depends solely on the Close values. A first buy indicator is referred to herein as “BB crossing,” for which Bollinger Bands (BB) of a given time-series includes two symmetric bands of 20-day data moving two standard deviations. The bands envelop the inherent stock volatility while filtering the noise in the price data. Traders may use the price channels as bounds for the trading activity around the price trend. Hence, when prices continually touch the lower band or go below that band, the prices may be deemed to be in an oversold position, thereby triggering a buying opportunity. Therefore, the BB buy signal may be defined to trigger when the daily Close value crosses above the lower band. In a similar manner, the BB crossing technique may be used to identify a sell indicator.

A second buy indicator is referred to herein as “MACD crossing,” for which a Moving Average Convergence Divergence (MACD) is a trend-following momentum indicator that compares the relationship between short and long exponential moving averages (EMA) of an asset. In an exemplary embodiment, the MACD may be computed by subtracting the 26-days EMA from the 12-days EMA. When the MACD falls to negative values, negative momentum is suggested; and conversely, when the MACD rises to positive values, upward momentum is indicated. A trader may prefer to wait for consistency in these measures, thus further smoothing the MACD line and computing the 9-days EMA of the MACD, which is also referred to as the “signal line”. In an exemplary embodiment, the MACD buy signal may be defined to trigger when the signal line crosses above. In a similar manner, the MACD crossing technique may be used to identify a sell indicator.

A third buy indicator is referred to herein as “RSI crossing,” for which a Relative Strength Index (RSI) is an oscillating indicator that summarizes the magnitude of recent price changes to evaluate overbought or oversold conditions of an asset. In an exemplary embodiment, the RSI may be computed as the ratio 14-day EMA of the incremental increase to the incremental decrease in asset values. The ratio may then be scaled to values that vary between zero (0) and one hundred (100); it rises as the number and size of daily gains increase, and it falls as the number and size of daily losses increase. A trader may use the RSI as an indication for an overbought state which might trigger a sell order or an oversold state which might trigger a buy order. In an exemplary embodiment, a threshold RSI value for indicating an oversold state is 30, and a threshold RSI value for indicating an overbought state is 70. Accordingly, in an exemplary embodiment, the RSI buy signal may be defined to trigger when the RSI line crosses above the value of RSI=30. In a similar manner, the RSI crossing technique may be used to identify a sell indicator.

In an exemplary embodiment, there are at least two different ways to detect a time-dependent signal in a static image. A first way is to label the image in a manner that indicates the time aspect. A second way is to augment the images with sequential features. In an exemplary embodiment, a box-and-whisker diagram may be labeled using an algorithm that relates to any of the BB crossing indicator, the MACD crossing indicator, and the RSI crossing indicator, where each computes a time-dependent function. Thus, by using a corresponding label, each image encapsulates the notion of time. In this regard, the signal to be detected is always located on the right-hand side of the image, as the cross-above trigger always occurs on the last day.

Referring to FIG. 5, three positively-labeled images that correspond to the BB crossing algorithm are shown. In an exemplary embodiment, these images may be generated by enveloping a 20-day interval of stock activity before and including the buy-signal day activity. In an exemplary embodiment, negatively-labeled images may be created from the same time series data by enveloping activity for days with no buy signal.

Referring to FIGS. 6A, 6B, 6C, 6D, and 6E, incorporating time-dependency via image augmentation may be achieved in various ways. For example, referring to FIG. 6A, the box-and-whisker notations may correspond to the daily HLOC values; and referring to FIG. 6B, the Close values may be displayed as a line plot. As another example, referring to FIG. 6C, the widths of the boxes in the box-and-whisker diagram may be linearly varied. As yet another example, referring to FIG. 6D, the previous Close values may be overlaid on each box-and-whisker notation. As still another example, referring to FIG. 6E, the widths of the boxes may vary according to the relative change of the trade volume within the corresponding time frame. As yet another example, the positively labeled images may be mirrored, together with their time-axes, and then the labels may be inverted. As still another example, the numerical time-series data may be transformed to a corresponding value-space, thereby producing recurrence plots by making time implicit.

In an exemplary embodiment, a standard time interval may be used for converting the time-series data into an image. For example, a 30-day trading window may be used for generating an image, regardless of which buy indicator algorithm is used.

In an exemplary embodiment, the time-series data image processing module 302 may be configured to use the historical data as training data, in order to obtain specific patterns that are deemed as useful for comparisons with subsequent data. In an exemplary embodiment, the historical data may be randomized and then divided into a set of training data and a set of testing data, which is used for validating the accuracy of the methodology. For example, the training data may include 80% of the historical data, and the remaining 20% of the data may be used for testing.

Accordingly, with this technology, an optimized process for implementing methods and systems for identifying signals or patterns in time series data by treating the series as an image is provided.
